Be it known that 1, lins HAMMER, citizen oit the United States, residing atv Grants Pass, in the 'county of Josephine and State of Oregon, have invented certain new and useful improvements in `Button-Attaching Machines, of which the following is a speciiieation.

This invention'relates to improvements in machines for attaching buttons, and has Jfor its object to provide a machine ot' this class in which the buttons shall he autour. tically ted from a slotted tube` by means of which they shalt he conveyed lo and held in the desired position while wire is being threaded through the eye ot' each successive liutton, to provide means for automatically paying oii wire tor each successive Istaple, by which the wire shall be severed and formed into staples. and by which the said staples shall he driven through the material or fab- `ric to which the huttons are' to be attached and clenched.

i tui-ther object is to produce a staple, the wire ot which shall 'present liat surfaces opposed to each other in the positions which hind upon the tabric to which it is attached.

The invention consists of the improved construction, arrangement, and combinationy of parts, which will be hereinafter full/y: de'l scrihed and particularly pointed out the claims.

Fig. 21 is a partial top View of the machine. Fig. 22 shows a detail of the wire reel. Similar characters oflreference indicate similar parts in each of the several views.

In the drawings, 3 represents a casing having a oor 6, mounted on supports 103 and 107, which are rigidly attached to base 109, havingan aperture' 110. .The said casing,` is inclined toward the front, as shown in Fig. 1S. The lower or front portion of the a track for the wire 41, coming from -the wire support 123, which is attached to casing 3 hy meansl of arm 125, the wire being inclosed between upper and lower disks, 120 and 127, which are separated by stays 119, all oi which are held in place by Cotter pin 124C.

The plunger 34 is slidably mounted within the casing, shown in Figs. 1 and-.2, and is provided with a depending lug 56, which operates within slot 84 in the floor 6.

livctally mounted on pin 98 in the lug 56 is a drive link 97 which is pivotally connected io bell crank 104 by means of pin 96. lSaid hell crank 104- is pivot-.lily moimted on pin 105 secured upon support 103.

At the upper end or' casing l is secured an overhanging arm 85, provided with an ori# lice 100, in which is secured the spring y, holder 101, which is adapted to retain ysprings 102, which are attached by their opposite ends to a similar spring holder 101, held within orifice 99, in hell crank 104'.

Said springs are adapted to retain plunger 34, at the upper end of the casing in normal position. The operating` ,.r'od 11.1 passes through the orilce 110 in the base 109, having the head 10S pivotally connected to the bell crank 101i, b v means of pin 100.

By apiilying` force downward upon rod 1.11, bell crank 104il is rocked on its pivot 105, thereby transmitting its motion through link 07 to the plunger 34, tori-.innr it downward tothe positionshorn in Figs and I8.

llnnger Bit is provided with lateral projcctimis 7 and 20 which form hearings ttor rod 8 on which is secured the spring retainer 22, adapted to hold springr 13, which abuts against 'asher l2 forcing rod S tothe position shown in Fig'. 1.

The plunger is cut away forming the not-ch l0, and the lower sidcof the body yhottoin 6 is raised slightly as at 40, to afford tace of the plunger also is cut away at formed therein, in any usual manner.

similar blade ed 1s secured in the side ofthe thereof adjacent the notch is rounded vso as'to form the cam surface 6l. The upper on' the side opposite the notch 16 to torni the cam surface 5.` The lower end of the plunger is slotted at 86 to receive the eye ot the button` l, and is further provided with notches 66 adapted to form the desired shape of head on the-staple 54C. 0n

the lateral faces of the lower end of the plunger are formed ribs 65.

Staple holder 2 is slidably held within `slot 87 formed in the casing 3, .and is pro- `videdfwithl the large longitudinal groove! G8 to receivethe lower end ofplunger 34, and provided with grooves '70 adapted to 4receive said ribs 'of the' plunger. Pin 69 'held .within the upper end of4 the holder 2, is adapted to pass transversely through slot 64, of the plunger, thus'causing a limited' movement of the holder during each reciprocation of the plunger.

' Upony a lateral face of'. the holder, at its lower extremity, is detachabl'y secured a vcutting blade 38, which is held Within a notl groove 37, Aata lpoint to `bear 'against the blade-38,' asit reciprocates.

Along side of the plunger, is pivotally fmounted the Wire eed-lever l0, upon the pivot pin 9,-engagin'g aperture 57. -,Flush with the upper face. thereofisthe cam engagin projection 15,'which is undercutI at 14. n the lower face of the wire` feedleve-r l0 is a down'wardly projecting pin .83

' working in slot 28 in the floor G, thereby the lateral movement of the lever is limited.- This teed-leveris held approximately parallel with plunger 34 by 'means 'of spring -27 surroundingpin 23 abutting at vone end against washerl, which is held in place by lug 18' at the inner face edge of case 3. the

other endheaif'ing against the lever 10 to -`vvhichthe pin E38 is pivotally attached in the slot 24s upon 'the pin 25, secured in oriice. 63. The oute.1 end if the pin 23- passes through the lug 18 and casing 3, when the `lever is vswung out by the action of cam 5 5o against the pdint l5.

t the lower end olilever l0, is hfingedly A. 'secured the wi11e-grip`-i6 by means of a-pin 39, engagedin orifice 59. The under side of the wire-grip is provided with a serrated 555" 'yieldingly'held inv engagement` therewith by f Vsurface 4.6., to engage the wire-41, and it is thespringl?, secured upon lever 10.

o y 1 Wire holder 451 attached to the floor G has formed on lts under side a serrated surface snnllarto that of the wi r'egr1} ),tl1e serra-A tions being inclined so as to' peru'iit a for.

4that when 4thevwireis'tforced down upon it,

.its face with a 'transverse groove 49, divided means of screws held within apertures .11.

Lessa-isz y In order to afford suiiicient force to cause the stapleholdcr 2 to sever the Wire /l-l when .cngagedbyblades 3 8 and 44, a swinging` stop 31 is pivotally mounted on plunger 3l, by 'means ot pin 2l in the 'orifice 62, and 1s.

. l7'0 adapted to abut against the adjacent cnd oli 'staple holder 2, thus allordingapositive' 'the downward movement ofA the retarding g5A :link 20 and thereby causingthelower end ctc' stop 31a' to swing outward and away from the upper end of staple' holder 2, thus allow# ingplunger 34, to xnove within the holder 2, Which nre'vious toth-is time had moved 90 with it,` A# staple former 42 is pivotally mounted upon pin 7l attached to the `Hoor 6, the yrear end of said staple former being curved upwardly at 5 2 so as to engage cam surface 61 of the plunger Se. `lThe upper face 'ofistaple former@ is recessed at 67, to'reccive a segment 54 of wire 4-1 to form a, staple, the forwardside of saidrecess being beveled so it will }ass11n1e theshape shownV in 5d". The 4 hcldcris beveledat 128 to contact with. cam surface l29ito forcethe former out oftheA line of movement of the plunger. :f I.'

Upon-.the front support v107 is formed the upwardly projecting anvil arm' 43 y carrying "on lits upper end anvil 5l, attached by means' of screws 55, which is preferably formed of. hardened'steelv 4The'anvil is provided upon 110 into .two parts by thel longitudinal central rib 50 and closed 4at'the outer ends by pio.

jections 48. l

lL-coverv 83- is attached'tothe case 3 by The. forward portion4 of the: cover is beveled at 98 andprovided with a slot' 126,.-Wheren the eyeo the button 1a lis. caused to slide until it reaches its intended position.l A button-chute 72 having attached on its lower surface -115.82, a support 87, is 'removably held within a socket'89. Said feeding tube is provided along its lower. side With-a slot- 73, to receive the eyes of buttons l?. Adit each side/of the' lower'end .of said tube, are formed slots Within whichstand` the" free ends .of spring '78, secured, upon' the exterior ofthe tube; the purpose Vthereof -being po-.arrest the buttons until ready to be selected'for use. A slot 79 'also is provided 130' noeaase in the upper surface of tube 72, the resulting prongs being bent inward as at 80, to further assist iinarresting the buttons.

Upon the cover 83 is pivotally mounted by means of 'screw 30a held within lug 86, a

bell crank 76, having in its horizontal armv 94, a slot 95 adapted to engage screw 30 which passes through a slot Soin the case 3 and is held in projection 29 of plunger 34. At the upper end of this bell crank is pivotaliy attached by means of pin 75, a ,feed bar 91 having secured near its lower end, a laterally projecting pin 81, adapted to be held against the upper surface of cam 92 by means of spring 77. A spring 88 attached to the cover 83 by screw 90 and to the upper arm of the bell crank 76, normally holds the latter in a forward position.

l his machine may be attached to a bench if desired. though I have shown it in use upon a stand 114 which is provided with a recess 116 adapted to receive the base 109, and which is further provided with button pockets 113 and tube pocket 112. The stand 114 is mounted upon a hollow support 115 having the legs 11T. i

'lo one of the legs at 121 is pivotally se cured foot lever 118, which pivotally is attached at 122 to the operating rod 111, connecting with bell crank 104.

The button feeding tube having previ-v ously been filled with buttons and the wire brought from the reel through the casing 3, under the wire-grip 4G and wire holder 45, through the eye of button 1 shown in position in l? ig. 1, and the fabric 53 to which the button is vto be attached being in place on the anvil, the operation of the machine is as follows: Power is applied to bell crank 104 through operating rod 111, by means of foot lever 118. 'C he motion thereof is transmitted through link 97 to the plunger 34; and as it pass-es downward, cam 5 contacts with point 15 of the wire feed-lever 10 throwing it outward against the spring 27, the wire holder 45 preventing the retraction of the wire. This movement also causes screw 3C- to operate bell crank 7G causing it to assume. the position shown in Fig. 18, where it is in position to force another button forward in the succeeding operation.4 As the plunger 34 continues downward the swinging stop 51@L forces the staple holder against the wire, causing it to sever a segment 54 and force it against theI staple former 42, so as to form the staple 541 which is held within slot in the staple holder 2. At this point. the stop 311'is forced to swing outward by `the retarding link 20, in the manner above described, thus allowing the pin 8 to come in yielding contact with holder 2, thus forciiig the latter against the fabric as shown in Fig. 18. At this point cam surface 01 has moved along the staple former suiliciently to permit the latter to rock on its shaft 71, so that the head 42 will drop out of the line of movement of the plunger. The plunger continuing its movement, drives the staple 54b through the fabric 58, and the ends of the staple striking the inwardly inclined projections 48, follow the groove 49 until they reach the rib 50, and the further movement of the plunger causes the top to settle leaving the staple formed as indicated at 54. It will be observed that the wire is half round in cross section as shown at 41, Fig. 12, and as it enters the casing it does so through a corresponding aperture which holds it in such position that the staple will always be formed with the fiat side inward. The foot lever being released springs 102 cause the bell crank 104 to force the plunger 34 back to its normal position. In its upward movement the lower end of slot 64 engages pin 69 carrying with it the holder 2. As soon as the holder has receded sufficiently to permit the return ofthe staple former, the cam 61, contacts with the projection 52, rocking the staple former on its pivot and bringing it into position again.l During the return movement of the plunger 34, bell crank 76 is rocked forward on its pivot 30a causing downward the feed bar 91 to force another button into position ready to receive the' end of wire 41,

after. which the cam 5 will have receded from the projection 15, thereby releasing the lever 10 and allowing it to swing forward, the grip at its end carrying the wire through the eye of the button to the position shown iu Fig. 1 ready to attach another button.
